1. High efficiency: This new ultrasonic sieve could reach to high-efficiency screening in a unit area.
2. High precision: This machine could be installed ultrasonic transducer in every layer that at most two layers to reach to high precision screening.
3. Self-cleaning machine: This ultrasonic sieve could reach to high precision but without blocks at the function of ultrasonic generator.
4. Multi-function ultrasonic sieve: This machine could solve the familiar problems such as strong adsorptivity, clot, high static and light specific gravity.
5. No destruction of material: This machine could not change the material nature in the screening process because of the ultrasonic wave.
